CHAIN.

Application filed June 18, 1926. Serial No. 116,869.

any desired intervals throughout the length of the chain.

In the drawing: 7

Figure 1 is a fragmentary view of the parts in the first step of the process, the view being partly in side elevation and partly in section;

Figure 2 is a section on line 2-2 of Fig. 1;

Figure 3 is a section on line 3-3 of Fig. 4 and r r t Figure 4 is a side elevation of the completed chain.

In proceeding in accordance with the present invention a chain 1 is employed, which may be of any preferred type or any flexiblecable or equivalent structure can be employed as desired. A series of preferably square tubular b xes or parts 2 are threaded over the chain or cable 1 and are arranged at any desired or selected interval along the length of the chain. The chain or cable and the boxes, are of such size as to permit the chain to be easily and quickly threaded through the boxes or parts 2. With the parts thus assembled and appearing as in Figures 1 and 2 of the drawings, the parts or boxes are then swedged so as to impart a substantially diamond shaped configuration thereto as shown in Figures 3 and 4 of the drawings. This swedging results in causing certain of the links of the chain to be distorted or compressed as shown in Figure 3, so as to thus form a tight frictional engagement between the chain links and the boxes, which engagement is such that the boxes are held against movement relative to the chain, while the boxes furthermore do not have their ornamental appearance detracted from.

The boxes 1 may be of any desired length, and by varying the spaces between adjacent boxes more or less of the chain 1 will be exposed as desired.

Having thus described myinvention, what I claim as new and. desire to secure by Let-' ters Patent is 1. In combination with a continuous flexible support, a series of boxes threaded over the support, said boxes having compressed parts which latter frictionably engage the support so as to hold the boxes against movement in both directions lengthwise of the support.

2. The herein described method of making ornamental chains, which resides in threading the chain through a series of spaced box es, the latter being of square cross section,

then in swedgingthe boxes so as to compress parts of the chain andparts of the boxes thereby to frictionally connect the boxes to the chain and to. impart a substantially diamond shaped cross section to the boxes.

3. The herein described method of making ornamental chains, which resides in thread ing the chain through a series of boxes, and then swedging the boxes to compress and thereby cause the same to friotionally engage the chain 4:. The herein described method of making ornamental chains which resides in thread ing the chain through a series-of boxes and then in swedging the boxes so as to compress parts of the chain and of the boxes so as to prevent movement of the boxes along the chain.

5. The herein described method of making ornamental chains and the like, which re sides in threading the chain through a series of boxes, then in disposing the boxes in predetermined spaced order along the chain length, and then in swedging the boxes to cause parts thereof to engage the chain so as to hold the boxes in said predetermined spaced order and against movement lengthwise of the chain.

In testimony whereof-I have signed my name to this specification.
